HELEN A. BLANGI-IARD, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR T0 UNIONSPECIAL MACHINE COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OFILLINOIS.

To all whom it may concern Be it known that I, HELEN A. BLANCHARD, acitizen'of the United States, residing at Philadelphia, in the county ofPhiladelphia, State of Pennsylvania, have invented certain new anduseful Improvements in Hat-Sewing Machines, of which the following is adescription, reference being had to the accompanying drawing and to thefigures of reference marked thereon.

The invention relates to new and useful improvements in sewing machines,and more particularly to machines of this class which are adapted forstitching the reed cover to a hat body.

An object of the invention is to provide a stitching mechanism, whereina reed cover may be stitched to a hat body by stitches passing throughthe reed cover and the hat body, which stitches may be comparativelywidely spaced. v

A further object of the invention is to provide a stitching mechanismfor the above purpose, wherein a single thread may be formed into a loopby an eye-pointed needle, and carried through the reed cover and hatbody to the outer face thereof, where said loop is transferred to a hookneedle and brought back again to the inner face of the hat body and reedcover, and interlocked by the next succeeding needle loop, as it ispassed through the hat body.

These and other objectswill in part be obvious, and will in part behereinafter more fully disclosed.

In the drawings, which show by way of illustration one embodiment of theinvention, Figure 1 is a rear side elevation of a sewing machineembodying my improve ments; Fig. 2 is a front side elevation there-,

of the parts of said operating mechanism being detached for the sake ofclearness. Fig. 9 is a view showing more or less diagram 1nat1cally,andin perspective, the stitch formlng elements with the needle at the lowerend of its stroke; Fig. 10 is a similar view showing the needle at theupper end of 1ts stroke; Fig. 11 is a similar view showing the hookneedle at the upper end of its stroke, and taking the loop from thelooper; Fig. 12 is a similar view showing the hook needle drawing theloop through the material, and the eye-pointed needle at substantiallythe lower end of its stroke; Fig. 13 is a detail in perspective showingthe lower position. of the hook needle, and the needle loop resting onthe spreader; and Fig. 1 1 is a detail perspective view, showing more orless diagrammatically, the stitch formed by my machine.

In carrying out the invention, I have provided a sewing machine which isformed with a supporting base 1, from which rises a standard 2, carryingan over-hanging arm 3. Also extending from the supporting base 1 is awork support 4. This work sup port, as clearly shown in Figs. 1, 2 and3, is curved on the arc of a circle. The cloth plate of the worksupport, on which the body of the hat rests during the stitchingoperation, is mounted on a bracket arm 5, carried by an extension 6,which is a part of the frame supported by the supporting base 1. Thiscloth plate is formed with slot 7, through which project the teeth 8 ofa rotatable feed wheel 9. This feed wheel 9 is mounted to turn upon apivotal support 10, which is carried by the bracket 5, on which thecloth plate is mounted. The feed wheel 9 is mounted so as to rotatefreely upon this pivotal support 10. Also mounted to turn freely on thepivot support 10 for the feed wheel is a collar 11. This collar 11 isformed with a radially projecting lug 12, see Fig. 5, and a radiallyprojecting arm 18, on which is pivotally supported a pawl 14, adapted tocooperate with a ratchet wheel 15, attached to, and moving with the feedwheel 9. The pawl 14 is held inengagement with the ratchet wheel by asuitable spring 16, which is connected at one end to the pawl, and atits other end to an arm or screw 17 mounted on the bracket 5. Thisspring not only holds the pawl in engagethe operating mechanismtherefor, certain'afment with the teeth of the ratchet wheel, but

also tends to swing the collar 11 on its support so as to bring the lug12 into contact with an arm 18 mounted on the shaft 19.

The shaft 19 is mounted at one end in a suitable bearing carried by thebracket 5, and at its other end, in a bearing 20, carried by thesupporting standard. This shaft is oscillated by a link 21, whichengages an eccentric on the main shaft 22. As the main shaft 22 isrotated through the belt wheel 23,. the shaft 19 will be oscillated,which will,

.in'turn", swing the arm 18 and, through the lug 16, move the collar 11,so as to cause the pawl 14 to turn the ratchet wheel 15, and therebyturn the feed wheel 9. Through this step by step movement of the ratchetwheel, the feed wheel is moved intermittently, and as the hat body restson said feed wheel, said hat body will be moved step by step to positionthe same for the successive stitches.

The hat body, indicated at H in Figs. 9 to 12, is inserted in themachine so that it rests on the work support 4, and the feed wheel 9engages the reed cover C at the inner face thereof. The rim R of the hatprojects upwardly substantially vertically during the stitchingoperation. The reed cover encircles the rim R, and-the purpose of mystitching machine is to baste or secure this reed cover to the hat body.The hat body is held on the work support, and against the feed wheel bya presser foot 24. This presser foot 24 is carried by a presser bar 25,mounted to slide vertically in suitable lugs carried at the) forward endof the over-hanging arm 3. A spring 26 normally holds the presser footdepressed against the outer surface of the hat body. A cam lever 27 issecured at the upper end of the presser bar and serves as a means forraising the presser foot. As a means for guiding the hat body to thestitching mechanism, 1 have provided a guiding shoe 28, which is mountedupon a circular plate 29, pivotally supported on a pin 30, carried bythe bracket 5. A handle 31 is attached to this plate and serves as ameans to move the same about its pivotal axis, so that the guiding shoe28 may be brought to a point opposite the stitching point, where thefeed wheel engages the hat body. The cloth plate is formed with adepression 32, which serves as a guide for the reed cover. The circularplate 29 is so spaced from the cloth plate that said circular plate willextend over the reed cover, and support the hat body, while the reed andreed cover are fed underneath this circular plate, and brought intocontact with the hat body only at the stitching point, or adjacentthereto. The guiding shoe 28 is mounted on a yielding segment 33, whichis pivotally secured at 34 to the circular plate 29. This yieldingsegment extends in advance of the edge of the circular plate 29.

The stitching mechanism consists of an eye-pointed needle 34, a hookneedle 35, and a looper 36. The eye-pointed needle 34 is carried by aneedle bar '37, which reciprocates in the lugs 38 and 39 carried by theframe of the machine. A lever 40 is pivoted at 41 to the frame and isconnected by a short link 42 to the needle bar 37. This lever 40 has aforwardly extending arm 43, carrying a ball stud, which is engaged by alink or eccentric strap 44, which, in turn, cooperates with an eccentricon the main shaft 22. The hook needle 35 is carried by a needle bar 45which is also mounted to reciprocate in the supporting lugs 38 and 39. Alever 46 is pivoted to the supporting stud 41 and is provided with arearwardly extending arm 47, carrying a ball stud, to which the link oreccentric strap 48 is connected, and this eccentric strap 48, in turn,coiiperates with an eccentric on the main shaft 22. The lever 46 isconnected by a short link 49 to the needle bar 45.

The looper 36, above referred to, is carried by an inclined shaft 49,which is mounted in a suitable bracket 50, bolted to: the forward end ofthe overhanging arm. The shaft 49 supporting the looper is parallel withthe longitudinal axis of the needle bar 37 and also the longitudinalaxis of the needle bar 45. This shaft, at theupper end, carries a bevelgear 51, which meshes with a segmental rack 52, pivoted at 53 to theoverhanging arm. The segmental rack 52 is pro vided with a slot 54. Themain shaft 22 extends through the overhanging arm and through the slot54. On the forward end of the main shaft 22 is a cam plate 55, which isadapted to contact with a roller 56, carried by a stud secured to thesegmental rack 52. This segmental rack, which is operated in onedirection by the cam 55, is controlled in the opposite direction by thespring 100, the end of which 101 bears upon this segmental rack. As themain shaft 22 rotates, the cam plate 55 contacting with the roller 56will oscillate the segment 52 about its pivotal support 53. Theoscillation of this segment will rotate the shaft 49 carrying thelooper, so as to cause said looper to engage the needle loop thrown outby the eye-pointed needle, and position the same so it will be engagedby the hook needle. The devices for operating the eye-pointed needle,the hook needle and the looper, are so timed relative to one anotherthat the looper thread thrown out by the eye-pointed needle istransferred to the hook needle, after which the hook needle descends,carrying the loop with it, through the hat body and the reed cover.

In order to assist the hook needle in positioning and supporting theloop of needle thread carried thereby, so that the eye-pointed needle asit ascends will pass into and through said loop, I have provided a loopspreader 57. This loop spreader 57 is adjustably mounted in an arm 58,see Fig. 6, carried by a shaft 59 mounted to oscillate in a lug 60carried by the frame of the machine. The shaft 59 at its outer endcarries an arm 61. A short shaft 62 is mounted in a suitable bearing inthe frame of the machine, and this short shaft carries a downwardlyprojecting lug 63, in which is adjustably mounted an arm 64. A rod 65engages a ball stud on the outer end of the arm 66L. The upper end ofthe rod 65 is adjustably secured to the head 66 carried at the lower endof a vertically reciprocating bar 67. This bar 67 slides in a suitablesupport 68. The upper end of the bar is forked and is provided with aroller 69 which engages a cam 70 on the main shaft 22. A spring 71encircles the bar 67 and bears at one end against the support 68, whilethe other end of the spring bears against the forked head at the upperend of the bar. This spring normally holds the roller 69 in contact withthe cam, and also holds the outer end of the arm 64 raised.

Mounted on the shaft 62 is an arm 72. As the main shaft rotates, the cam70 through the bar 67 and the rod 65 will oscillate the shaft 62, whichwill move the arm 72 up and down. A link 7 8 is pivoted to the outer endof the arm 72. This link at its other end is pivoted to a studadjustably mounted in a slot 74: in the lower end of the arm 61, whichis connected with the shaft 60 on which the spreader is supported. Athread ed bolt 75 extends lengthwise of the slot 74:, and the stud towhich the link 7 3 is pivoted is carried by this threaded bolt. Saidthreaded bolt is formed with spaced collars 7 G, and has a head 77 atits lower end, through which the threaded bolt may be turned. By turningthe threaded bolt, the stud is moved lengthwise of the slot and therebythe stroke of the spreader varied.

The thread is supplied to the needle from a spool 78 carried by asuitable supporting pin 79 on the overhanging arm; The thread passesfrom the supply through a suitable tension 80, and thence to a threadguide 80 on the needle lever 40 and then through a guide 81 carried onthe upper supporting lug 38, in which the needle bar reciprocates.

A finger S2 is adjustably mounted on an arm 83 carried by a shaft 84.Said shaft 84: is bored transversely thereof, and the arm 88 extendsinto said opening. A screw 85 engages the arm and holds the same inadjusted positions in the shaft 84. This shaft is mounted to turn freelyin a sleeve 86, which is clamped to a suitable slotted bracket 87mounted on the frame of the machine. The other end of the shaft 84carries an arm 87 which projects downwardly therefrom. This arm 87 (seeFig. 8), is pivotally connected to a link 88, which in turn is pivotallyconnected to the slotted arm 89 of a rock shaft 90 pivoted to thesupporting frame. The other arm 91 of the rock shaft is pivotallyconnected to a link 92. This link 92 is pivotally connected at its upperend to a lever 93, fulcrumed at 94 on a bracket 95 mounted on the headof the machine. .This lever 93 is adapted to engage a cam 96 on the mainshaft 92. A spring 97 engages the under face of the lever and normallyholds said lever pressed into contact with the cam.

The operation of my device will be apparent from the diagrammatic viewsshown in Figs. 9 to 13. The hat body to which the reed cover is to bebasted or stitched, is placed on the cloth support 4:, and the presserfoot lowered so as to'engage the outer face thereof. The reed and reedcover are fed underneath the circular plate 29, through the guidingrecess 32. The guiding shoe 38 is brought to a point opposite thestitching mechanism, so as to engage the rim of the hat body and guidethe same. The pointed needle 34 is raised and penctrates the reed coverand hat body As soon as the needle reaches the upper end of its stroke(see Fig. 10), the looper 36 is moved into the needle loop thrown out asthe needle is slightly retracted, and this loop is carried by the looperto a position where the retracting movement of the hook needle 35 causesthe hook thereof to engage the loop, (see Fig. 11). As soon as the hookneedle is well engaged into the needle loop, the looper is retracted, soas to release the needle loop, and the hook needle moves down Ward withthe eye-pointed needle, carrying the loop engaged thereby down throughthe hat body and the reed cover through the opening formed by the hookneedle. As soon as the hook needle moves out of the hat body and reedcover, the feed wheel 9 is moved to position the hat body for the nextstitching operation. This movement of the hat body carries the base ofthe needle loop forward, and this movement of the base of the needleloop, together with the downward movement of the hook needles, lays saidloop on to the loop spreader 57. This loop spreader is formed with aforked forward end 98. The upper arm of the fork is slightly raised,thus forming a shoulder 99 in the rear thereof. This loop spreader isalso moved forward during this position ing of the needle loop, and as aresult of these combined movements, one strand of the needle loop islaid into the forked end 98 of the loop spreader. The needles are timedso that the eye-pointed needle rises first, and as soon as the pointthereof is well into the needle loop held by the hook needle and theloop spreader, then the hook needle also rises and the spreader isretracted, so that the needle loop is dropped, and I this needle loop isnow around the shank of the needle which penetrates the hat body to formthe next stitch. The finger 82 is so timed as to move against the strandof the needle loop extending between the hook of the needle andthespreader, and presses said strand backward away from the point of thehook needle, as the hook needle rises, and thus prevents the hook needlefrom entering its own loop, and enables the needle loop to be shed fromsaid hook needle. The threads are drawn taut, and the stitch set by themovement of the thread eye on the needle lever. The eye-pointed needlereaches the upper end of its stroke slightly in advance of the hookneedle, and the hook needle reaches the upper end of its stroke in timeto take the loop from the looper for the formation of the next stitch.

In Fig. It I have shown more or less diagrammatically the stitch formedby the above described mechanism. The thread T is formed into a loop 2.which is carried up through the work, thence laterally in the line offeed, and thence downwardly through the fabric, where the .next loopformed by the needle passes through the first named loop and thenthrough the fabric for forming the next stitch. It will be noted thatthe hook needle and the, eyepointed needle are substantially in linewith the line of feed. The throw of the feed wheel 9 is such as tocomparatively widely space the stitches, and I have thereby provided astitching mechanism wherein the reed cover may be basted or stitched tothe hat body by a series of loops, which are passed from the inner faceof the hat body to the outer face thereof, and then returned through thehat body and reed cover, to the inner face, where it. is locked by thenext needle loop which is passed through the hat body to form the nextsucceeding stitch. These interlocked needle loops extend insubstantially the line of feed. 7

From the above, it will be noted that the needle bars 37 and 45areparallel. When the needles move through the fabric, inasmuch as theyare parallel, the looper 36,

which cooperates with these needles, may be set at some distance abovethe material as the needles are always the same distance apartlaterally. This gives plenty of room for the manipulation of the articlebeing stitched and readily permits the insertion of the same between thelooper 36 and the work support, Furthermore, when the needles areretracted and are beneath the work support they are close together and aspreader may engage the loop of needle thread carried by the hook needleand open the same for the entrance of the eye-pointed needle. 7Attention is called particularly to these functions of the placing ofthe needles parallel, as such functions are not found in the type ofstitching machine wherein needle bars move in lines at an angle to eachother instead of parallel.

While I have described my machine as especially adapted for stitching a.reed into a hat body, it will also be obvious that the reed may bestitched to the hat sweat on my machine. When stitching the reed to ahat sweat, the hat sweat stands upright, the

same as the rim of the hat, and the reed. portion is turned under thepresser foot, where it is basted or stitched to the reed covering. Itwill also be obvious that my machine may be used for other purposes thanstitching hats, and in fact for all classes of work in which theparticular stitch above described is desirable.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is
